	What is dots per inch? - a definition from Whatis.com - see also: dpi
		1) In computers, dots per inch (dpi) is a measure of the sharpness (that is, the density of illuminated points) on a display screen.
		The dots per inch for a given picture resolution will differ based on the overall screen size since the same number of pixels are being spread out over a different space.
		Some users prefer the term "pixels per inch (ppi)" as a measure of display image sharpness, reserving dpi for use with the print medium.

	cars - Dots per inch
		Dots per inch (DPI) is a measure of printing resolution, in particular the number of individual dots of ink a printer or toner can produce within a linear one-inch space.
		Each dot on a printer can be one of only four colors, while each pixel on a video monitor can be one of several million colors; printers must produce additional colors through a halftone or dithering process.
		An image that is 100 pixels wide may need to be 400 to 600 dots in width in the printed output; if a 100×100-pixel image is to be printed inside a one-inch square, the printer must be capable of 400 to 600 dots per inch in order to accurately reproduce the image.

	Photos/Pictures of DPI (Dots per Inch)
		Getting down to basics, DPI stands for "dots per inch," and it refers to the number of pixels that represents one American "Inch." (Apologies to those countries that use the infinitely more rational metric system.) In the digital imaging world, DPI comes up in two major contexts: input and output.
		The film may be only an inch wide, but you want to print it on a full-sized sheet of paper; you need to know what the DPI is on the scanner, so you can translate it to values that make sense for the printer.
		If the printer is going to make wallpaper, chances are that it only prints 50 pixels per inch of paper, in which case, the same 5000 pixels will produce 100 inches of that image.

	Design215 Photography Printing Guide - DPI vs PPI
		Even though "dots per inch" (dpi) and "pixels per inch" (ppi) are used interchangeably by many, they are not the same thing.
		Dots per inch (dpi) refers to printed dots and the space between them, while pixels per inch (ppi) refers to the square pixels in a digital image.
		A real photograph made from film in a darkroom has no dots or pixels and therefore is the standard by which "photo quality" is judged.

	DPI Or Dots Per Inch
		DPI represents the number of dots per linear inch to be scaled from hard copy media in preparation for a scanning job.
		PPI stands for Pixels Per Inch and represents the number of pixels per linear inch on a photo print when a digital image's pixels are scaled onto paper.
		Mathmatically speaking, 72 dpi dots are 1/72 of an inch in diameter and 300 dpi dots are 1/300 of an inch diameter.

	International Paper - Line Screens
		"Dots" has become the generic term applied to all of the dot structures used to create the halftone, regardless of whether the dot shape is square or grain texture.
		Traditional line screens are referred to as amplitude-modulated (AM) screens having dots which vary in size, according to the number of lines per inch, and are aligned in columns and rows.
		With an increase in the lines per inch, which increases the number of smaller dots in the line screen, there is a corresponding increase in the detail within the image but a decrease in the shades of gray.

	Dots per inch - Wikipedia, the free encyclopedia
		At each dot position, the simplest type of colour printer can only either print no dot, or a dot consisting of a fixed volume of ink in each of four colour channels (typically CMYK).
		A digital image captured by a scanner or digital camera may have an intended resolution (in pixels per inch), but this need not correspond to the DPI at which it is printed.
		For example, a 1000×1000-pixel image could be printed at 4×4 inches and 250 pixels per inch, or at 10×10 inches and 100 pixels per inch.

		Lines per inch is the terminology used in offset printing, which uses a line screen to break up continuous tone material into halftone dots.
		Dots per inch is the terminology used by laser and inkjet printers.
		Instead, knowing that 300 pixels per inch will produce excellent output with these printers, we would divide the true optical resolution of the original file by 300 pixels per inch on the short side of the print and see that we had enough true resolution to output 9 inches (2700 PPI / 300 PPI).

		In other words, if the dots per inch are increased, the printed image will decrease in size (and the quality may increase); if the dots per inches are decreased, the printed image will increase in size (and the quality may decrease).
		For example, if the dots across are 1,200, then there are 300 dpi per color (four divided into 1,200 is 300 dpi; as four colors to create a print — fl, magenta, cyan and yellow).

		Dots per inch is just a measure of how dense the dots (pixels) are packed into a given space.
		A setting of 300 dots per inch will, with a good printer, result in a print that is sharp and detailed even when viewed with your nose nearly touching the paper.
		Dots per inch (DPI) or pixels per inch (PPI) are just a measure of how big the pixels are, which will then relate to how many of them will fit in an inch.

	resolution
		The technical term for the number of pixels per linear inch of this input image is ppi (pixels per inch) or spi (samples per inch).
		However, a printer, that has a maximum resolution of 720 x 720 is commonly stated as having a dpi of 720 (however, usually it is not as high as stated although it is not done to mislead the user).
		The home user does not have to concern himself with lines per inch other than to recognize that the common relationship of ppi to lpi is 2:1.

		As an example, there are 75 half-tone dots per inch (lpi) in a newspaper, 133 half-tone dots per inch (lpi) in a magazine or 175 half-tone dots per inch (lpi) in a high quality brochure.
		True at 75 dots per inch (lpi), there is room for only 75 equally spaced areas for half-tone dots per inch in a newspaper --BUT there are many different sizes of these dots which can fit into each designated area.
		Because the dot sizes are all of the same size on most printers, in very light areas the cyan and magenta would be very noticeable.

	Hardware - Monitor2
		For a standard CRT, the horizontal dot pitch equals 0.866 times the diagonal pitch, which comes to 0.2252mm horizontal measurement for a 0.26mm diagonal pitch; this calculation is derived from the geometric properties of equilateral triangles.
		Since the actual physical dots on the screen are rarely ever referred to - when you hear the term, "dots per inch" it is usually speaking of print resolution - or it can wrongly mean pixels per inch (ppi) since the term is so loosely thrown around.
		Resolution is not equal to the Dot Triad we mentioned before, nor is it equal to dot pitch - both of these measurements are fixed, and are dictated by the way the shadow mask or aperature grill was made.

	Pixels per inch - Wikipedia, the free encyclopedia
		Pixels per inch (PPI) or pixel density is a measurement of the resolution of a computer display, related to the size of the display in inches and the total number of pixels in the horizontal and vertical directions.
		This measurement is often referred to as dots per inch, though that measurement more accurately refers to the resolution of a computer printer.
		For example, a display that is 11 inches wide by 8.5 inches high, capable of a maximum 1024 by 768 pixel resolution, can display about 93 PPI in both the horizontal and vertical directions.

	SCANNING For Web and Printer
		Resolution means how many dots of graphic information per inch to capture, so resolution is expressed as "dpi" or dots per inch, also called pixels per inch or "ppi." Dots per inch (dpi) affects the image size and the file size.
		Due to the relatively high dots per inch capability of a printer, you can usually scan at a lower resolution than you will print at and not notice much reduction in print quality.
		If, for example, 10 dots in a row are a very slightly different shade of Red, the JPG compression may save them all as the same color to save space.

		For example, a 300-dpi (dots per inch) printer is one that is capable of printing 300 distinct dots in a line 1 inch long.
		Quite simply, we're looking at the difference between how many dots per inch the computer is trying to display and how many dots per inch the monitor can show before they start running into each other.
		That doesn't mean that dot pitch isn't a good indicator of screen sharpness, only that it doesn't directly predict with the maximum sharp display setting.

		OK, so you've bought a new scanner that can scan at 1200 dots per inch and you're determined to use it to the full.
		A square inch would thus consume 120 KB and a 6x4 picture would be 2.88 MB.
		To end up with 200 dots per inch for printing, you'd thus need to scan at 600 dots per inch.

		The finer the halftone screen- that is the more halftone dots per linear inch the screen produced, the higher the quality of the image printed- that is, there was higher detail.
		The smaller dots look like they are a lighter shade of grey than the larger ones, but this is an artifact of the scanning process.
		One mathematical technique is called ‘error diffusion dither.’ While the technique does allow a much better image quality with a given number of printer dots per inch, it still, on the average, takes a number of printer dots to equal one pixel.
